Building a rain sensing alarm with Arduino.

In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code.

In this tutorial, you will learn how to calibrate and use MQ9 gas sensor with an Arduino board.

This little project will show you how to use a soil moisture sensor.

Read data from an absolute orientation sensor without writing any code!

This project will show you how to use temperature and hmidity (DHT11 and DHT22) sensors with an Arduino card.

If there will be no traffic on the other signal, one shouldn’t wait for that signal. System will skip that signal and will move on next one.

I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

Ultra low-cost flow-through photometer for on-line measurements of bacterial density.

A standard speaker can be used to detect vibrations and send data to a microcontroller.

This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.

Using ultrasonic sensors to measure distance of obstacles, taking into account temperature and humidity that affect the speed of sound.

I've always wondered if there were any real differences between temperature and humidity sensors, especially DHT11 and DHT22.

Temperature and humidity control to achieve the ideal confort conditions. The system work in a automatic way without a manual control.

This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed.

This project shows tilt sensors and its functions.

This projects detects knock using Arduino UNO and sends notification to Windows 10, Ubuntu.

An IoT device to automatically switch on/off electronic appliances based on the availability of human beings, especially in public services.

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.

MQ2 Sensor is a gas module and it is suitable to detect Hydrogen, LPG, Smoke, CO, and Alcohol. It has high sensitivity and fast response.

Air meter making, a second time! Let's look at temperature and humidity using the DHT 11 module.

The Arduino 9 Axes Motion Shield allows your Arduino to measure movement: orientation, acceleration and magnetic field.

A basic introduction to the low cost and accurate HC-SR04!

This tutorial shows you how to control the screen brightness automatically. I use the LattePanda as a PC. Hope you like it.
